mug chugging
when you really hate someone's fucking guts so bad that you offer to make them a cup of coffee and before you pour you rub your dirty sweaty cheesy balls all over the rim of the cup
hmmm . . . great cup of coffee you made there grant . . . but was the milk off cause I have a cup full of cheese !
Mug and Chug
Enjoying a beverage, usually coffee or beer, while receiving oral sex.
I came home from a long day of work and my wonderful girlfriend greeted me with a mug and chug.
